Impurity-controlled vortex mobility and pair-breaking in fermionic superfluid rings
BuÄra Tüzemen, Andrea Barresi, Gabriel WlazÅowski +2
Using time-dependent density functional theory, we study how density and size of impurities govern dissipation of persistent currents of fermionic superfluid rings in the BCS regim…
Reproducible nucleation and control of stable quantum vortex rings in Bose-Einstein condensates
Giorgia Iori, Klejdja Xhani, Woo Jin Kwon +2
We propose and numerically validate an experimentally feasible on-demand protocol for the nucleation and manipulation of stable quantum vortex rings in trapped Bose-Einstein conden…
Tuning the Critical Current in Toroidal Superfluids via Controllable Impurities
K. Xhani, G. Del Pace, N. Grani +4
We combine numerical and experimental approaches to study how impurities affect the maximum superflow in an annular Bose-Einstein condensate. By tuning the impurity density, we ach…
Stability of persistent currents in superfluid fermionic rings
Klejdja Xhani, Andrea Barresi, Marek Tylutki +2
We investigate the stability of persistent currents in superfluid fermionic gases confined to a ring geometry. Our study, conducted at zero temperature using time-dependent density…
